This is a log of changes that ncurses has gone through since Zeyd started
Changes through 1.9.9e did not credit all contributions;
it is not possible to add this information.
+20170826
+ + fixes for "iterm2" (report by Leonardo Brondani Schenkel) -TD
+ + corrected a warning from tic about keys which are the same, to skip
+ over missing/cancelled values.
+ + add check in tic for unnecessary use of "2" to denote a shifted
+ special key.
+ + improve checks in trim_sgr0, comp_parse.c and parse_entry.c, for
+ cancelled string capabilities.
+ + add check in _nc_parse_entry() for invalid entry name, setting the
+ name to "invalid" to avoid problems storing entries.
+ + add/improve checks in tic's parser to address invalid input
+ + add a check in comp_scan.c to handle the special case where a
+ nontext file ending with a NUL rather than newline is given to tic
+ as input (Redhat #1484274).
+ + allow for cancelled capabilities in _nc_save_str (Redhat #1484276).
+ + add validity checks for "use=" target in _nc_parse_entry (Redhat
+ #1484284).
+ + check for invalid strings in postprocess_termcap (Redhat #1484285)
+ + reset secondary pointers on EOF in next_char() (Redhat #1484287).
+ + guard _nc_safe_strcpy() and _nc_safe_strcat() against calls using
+ cancelled strings (Redhat #1484291).
+ + correct typo in curs_memleaks.3x (Sven Joachim).
+ + improve test/configure checks for some curses variants not based on
+ X/Open Curses.
+ + add options for test/configure to disable checks for form, menu and
+ panel libraries.
+
+20170819
+ + update "iterm" entry -TD
+ + add "iterm2" entry (report by Leonardo Brondani Schenkel) -TD
+ + regenerate llib-* files.
+ + regenerate HTML manpages.
+ + improve picsmap test-program:
+ + reduce memory used for tsearch
+ + add report in log file showing cumulative color coverage.
+ + add -x option to clear/tput to make the E3 extension optional
+ (cf: 20130622).
+ + add options -T and -V to clear command for compatibility with tput.
+ + add usage message to clear command (Debian #371855).
+ + improve usage messages for tset and tput.
+ + minor fixes to "RDGB" extension and reset_color_pairs().
+
+20170812
+ + improve description of -R option in infocmp manual page (report by
+ Stephane Chazelas).
+ + add reset_color_pairs() function.
+ + add user_caps.5 manual page to document the terminfo extensions used
+ by ncurses.
+ + improve build scripts, using SIGQUIT vs SIGTRAP; add other configure
+ script fixes from work on xterm, lynx and tack.
+ + modify install-rule for ncurses-examples to put the data files in
+ /usr/share/ncurses-examples
+ + improve tracemunch, by changing address-parameters of add_wch(),
+ color_content() and pair_content() to dummy parameters.
+ + minor optimization to _nc_change_pair, to return quickly when the
+ current screen is marked for clearing.
+ + in-progress changes to improve performance of test/picsmap.c for
+ loading image files.
+ + modify allocation for SCREEN's color-pair table to start small, grow
+ on demand up to the existing limit.
+ + add "RGB" extension capability for direct-color support, use this to
+ improve color_content().
+ + improve picsmap test-program:
+ + if no palette file is needed, attempt to load one based on $TERM,
+ checking first in the current directory, then by adding ".dat"
+ suffix, and finally in the data-directory, e.g.,
+ /usr/share/ncurses-examples
+ + add "-l" option for logging
+ + add "-d" option for debugging
+ + add "-s" option for stepping automatically through list of images,
+ with time delay.
+ + use tsearch to improve time for loading color table for images.
+ + update config.guess, config.sub from
+ http://git.savannah.gnu.org/cgit/config.git
+
+20170729
+ + update interix entry using tack and SFU on Windows 7 Ultimate -TD
+ + use ^? for kdch1 in interix (reported by Jonathan de Boyne Pollard)
+ + add "rep" to xterm-new, available since 1997/01/26 -TD
+ + move SGR 24 and 27 from vte-2014 to vte-2012 (request by Alain
+ Williams) -TD
+ + add a check in newline_forces_scroll() in case a program moves the
+ cursor outside scrolling margins (report by Robert King).
+ + improve _nc_tparm_analyze, using that to extend the checks made by
+ tic for reporting inconsistencies between the expected number of
+ parameters for a capability and the actual.
+ + amend handling of repeat_char capability in EmitRange (adapted from
+ report/patch by Dick Wesseling):
+ + translate the character to the alternate character set when the
+ alternate character set is enabled.
+ + do not use repeat_char for characters past 255.
+ + document "_nc_free_tinfo" in manual page, because it could be used in
+ tack for memory-leak checking.
+ + add "--without-tack" configure option to refine "--with-progs"
+ configure option. Normally tack is no longer built in-tree, but
+ a few packagers combine it during the build. If term_entry.h is
+ installed, there is no advantage to in-tree builds.
+ + adjust configure-script to define HAVE_CURSES_DATA_BOOLNAMES symbol
+ needed for tack 1.08 when built in-tree. Rather than relying upon
+ internal "_nc_" functions, tack now uses the boolean, number and
+ string capability name-arrays provided by ncurses and SVr4 Unix
+ curses. It still uses term_entry.h for the definitions of the
+ extended capability arrays.
+ + add an overlooked null-pointer check in mvcur changes from 20170722
+
+20170722
+ + improve test-packages for ncurses-examples and AdaCurses for lintian
+ + modify logic for endwin-state to be able to detect the case where
+ the screen was never initialized, using that to trigger a flush of
+ ncurses' buffer for mvcur, e.g., in test/dots_mvcur.c for the
+ term-driver configuration.
+ + add dependency upon ncurses_cfg.h to a few other internal header
+ files to allow each to be compiled separately.
+ + add dependency upon ncurses_cfg.h to tic's header-files; any program
+ using tic-library will have to supply this file. Legacy tack
+ versions supply this file; ongoing tack development has dropped the
+ dependency upon tic-library and new releases will not be affected.
+
+20170715
+ + modify command-line parameters for "convert" used in picsmap to work
+ with ImageMagick 6.8 and newer.
+ + fix build-problem with tack and ABI-5 (Debian #868328).
+ + repair termcap-format from tic/infocmp broken in 20170701 fixes
+ (Debian #868266).
+ + reformat terminfo.src with 20170513 updates.
+ + improve test-packages to address lintian warnings.
+
+20170708
+ + add a note to tic manual page about -W versus -f options.
+ + correct a limit-check in fixes from 20170701 (report by Sven Joachim).
+
+20170701
+ + modify update_getenv() in db_iterator.c to ensure that environment
+ variables which are not initially set will be checked later if an
+ application happens to set them (patch by Guillaume Maudoux).
+ + remove initialization-check for calling napms() in the term-driver
+ configuration; none is needed.
+ + add help-screen to test/test_getstr.c and test/test_get_wstr.c
+ + improve compatibility between different configurations of new_prescr,
+ fixing a case with threaded code and term-driver where c++/demo did
+ not work (cf: 20160213).
+ + the fixes for Redhat #1464685 obscured a problem subsequently
+ reported in Redhat #1464687; the given test-case was no longer
+ reproducible. Testing without the fixes for the earlier reports
+ showed a problem with buffer overflow in dump_entry.c, which is
+ addressed by reducing the use of a fixed-size buffer.
+ + add/improve checks in tic's parser to address invalid input
+ (Redhat #1464684, #1464685, #1464686, #1464691).
+ + alloc_entry.c, add a check for a null-pointer.
+ + parse_entry.c, add several checks for valid pointers as well as
+ one check to ensure that a single character on a line is not
+ treated as the 2-character termcap short-name.
+ + fix a memory leak in delscreen() (report by Bai Junq).
+ + improve tracemunch, showing thread identifiers as names.
+ + fix a use-after-free in NCursesMenu::~NCursesMenu()
+ + further amend incorrect calls for memory-leaks from 20170617 changes
+ (report by Allen Hewes).
+
+20170624
+ + modify c++/etip.h.in to accommodate deprecation of throw() and
+ throws() in c++17 (prompted by patch by Romain Geissler).
+ + remove some incorrect calls for memory-leaks from 20170617 changes
+ (report by Allen Hewes).
+ + add test-programs for termattrs and term_attrs.
+ + modify _nc_outc_wrapper to use the standard output if the screen was
+ not initialized, rather than returning an error.
+ + improve checks for low-level terminfo functions when the terminal
+ has not been initialized (Redhat #1345963).
+ + modify make_hash to allow building with address-sanitizer,
+ assuming that --disable-leaks is configured.
+ + amend changes for number_format() in 20170506 to avoid undefined
+ behavior when shifting (patch by Emanuele Giaquinta).
+
+20170617
+ + fill in some places where TERMTYPE2 vs TERMTYPE was not used
+ (report by Allen Hewes).
+ + use ExitTerminfo() internally in error-exits for ncurses' setupterm
+ to help with leak checking.
+ + use ExitProgram() in error-exit from initscr() to help with leak
+ checking.
+ + review test-programs, adding checks for cases where the terminal
+ cannot be initialized.
+
+20170610
+ + add option "-xp" to picsmap.c, to use init_extended_pair().
+ + make simple performance fixes for picsmap.c
+ + improve aspect ratio of images read from "convert" in picsmap.c
+
+20170603
+ + add option to picsmap to use color-palette files, e.g., for mapping
+ to xterm-256color.
+ + move the data in SCREEN used for the alloc_pair() function to the
+ end, to restore compatibility between ncurses/ncursesw libtinfo
+ (report/patch by Miroslav Lichvar).
+ + add build-time utility "report_offsets" to help show when the various
+ configurations of tinfo library are compatible or not.
+
+20170527
+ + improved test/picsmap.c:
+ + lookup named colors for xpm files in rgb.txt
+ + accept blanks in color-keys for xpm files.
+ + if neither xbm/xpm work, try "convert", which may be available.
+
+20170520
+ + modify test/picsmap.c to read xpm files.
+ + modify package/debian/* to create documentation packages, so the
+ related files can be checked with lintian.
+ + fix some typos in manpages (report/patch by Sven Joachim).
+
+20170513
+ + add test/picsmap.c to fill in some testing issues not met by dots.
+ The initial version reads X bitmap (".xbm") files.
+ + repair logic which forces a repaint where a color-pair's content is
+ changed (cf: 20170311).
+ + improve tracemunch, showing screenXX pointers as names.
+
+20170506
+ + modify tic/infocmp display of numeric values to use hexadecimal when
+ they are "close" to a power of two, making the result more readable.
+ + improve discussion of portability in curs_mouse.3x
+ + change line-length for generated html/manpages to 78 columns from 65.
+ + improve discussion of line-drawing characters in curs_add_wch.3x
+ (prompted by discussion with Lorinczy Zsigmond).
+ + cleanup formatting of hackguide.html and ncurses-intro.html
+ + add examples for WACS_D_PLUS and WACS_T_PLUS to test/ncurses.c
+
+20170429
+ + corrected a case where $with_gpm was set to "maybe" after CF_WITH_GPM,
+ overlooked in 20160528 fixes (report by Alexandre Bury).
+ + improve a couple of test-program's help-messages.
+ + corrected loop in rain.c from 20170415 changes.
+ + modify winnstr and winchnstr to return error if the output pointer is
+ null, as well as adding a null pointer check of the window pointer
+ for better compatibility with other implementations.
+ + improve discussion of NetBSD curses in scr_dump.5
+ + modify LIMIT_TYPED macro in new_pair.h to avoid changing sign of the
+ value to be limited (reports by Darby Payne, Rob Boudreau).
+ + update config.guess, config.sub from
+ http://git.savannah.gnu.org/cgit/config.git
+
+20170422
+ + build-fix for termcap-configuration (report by Chi-Hsuan Yen).
+ + improve terminfo manual page discussion of control- and graphics-
+ characters.
+ + remove tic warning about "^?" in string capabilities, which was
+ marked as an extension (cf: 20000610, 20110820); however all Unix
+ implementations support this and X/Open Curses does not address it.
+ On the other hand, termcap never did support this feature.
+ + correct missing comma-separator between string capabilities in
+ icl6402 and m2-nam -TD
+ + restore rmir/smir in ansi+idc to better match original ansiterm+idc,
+ add alias ansiterm (report by Robert King).
+ + amend an old check for ambiguous use of "ma" in terminfo versus
+ a termcap use, if the capability is cancelled to treat it as number.
+ + correct a case in _nc_captoinfo() which read "%%" and emitted "%".
+ + modify sscanf calls in _nc_infotocap() for patterns "%{number}%+%c"
+ and "%'char'%+%c" to check that the final character is really 'c',
+ avoiding a case in icl6404 which cannot be converted to termcap.
+ + in _nc_infotocap(), add a check to ensure that terminfo "^?" is not
+ written to termcap, because the BSDs did not implement that.
+ + in _nc_tic_expand() and _nc_infotocap(), improve string-length check
+ when deciding whether to use "^X" or "\xxx" format for control
+ characters, to make the output of tic/infocmp more predictable.
+ + limit termcap "%d" width to 2 digits on input, and use "%2" in
+ preference to "%02" on output.
+ + correct terminfo/termcap conversion of "%02" and "%03" into "%2" and
+ "%3"; the result repeated the last character.
+ + add man/scr_dump.5 to document screen-dump format.
+
+20170415
+ + modify several test programs to use new popup_msgs, adapted from
+ help-screen used in test/edit_field.c
+ + drop two symbols obsoleted in 2004: _nc_check_termtype, and
+ _nc_resolve_uses
+ + fix some old copyright dates (cf: 20031025).
+ + build-fixes for test/savescreen.c to work with AIX and HPUX.
+ + minor fix to configure script, adding a backslash/continuation.
+ + extend TERMINAL structure for ABI 6 to store numbers internally as
+ integers rather than short, by adding new data for this purpose.
+ + more fixes for minor memory-leaks in test-programs.
+
+20170408
+ + change logic in wins_nwstr() to avoid addressing data past the output
+ of mbstowcs().
+ + correct a call to setcchar() in Data_Entry_w() from 20131207 changes.
+ + fix minor memory-leaks in test-programs.
+ + further improve ifdef in term_entry.h for internal definitions not
+ used by tack.
+
+20170401
+ + minor fixes for vt100+4bsd, e.g., delay in sgr for consistency -TD
+ + add smso for env230, to match sgr -TD
+ + remove p7/protect from sgr in fbterm -TD
+ + drop setf/setb from fbterm; setaf/setab are enough -TD
+ + make xterm-pcolor sgr consistent with other capabilities -TD
+ + add rmxx/smxx ECMA-48 strikeout extension to tmux and xterm-basic
+ (discussion with Nicholas Marriott)
+ + add test-programs sp_tinfo and extended_color
+ + modify no-leaks code for lib_cur_term.c to account for the tgetent()
+ cache.
+ + modify setupterm() to save original tty-modes so that erasechar()
+ works as expected. Also modify _nc_setupscreen() to avoid redundant
+ calls to get original tty-modes.
+ + modify set_curterm() to update ttytype[] data used by longname().
+ + modify wattr_set() and wattr_get() to return ERR if win-parameter is
+ null, as documented.
+ + improve cast used for null-pointer checks in header macros, to
+ reduce compiler warnings.
+ + modify several functions, using the reserved "opts" parameter to pass
+ color- and pair-values larger than 16-bits:
+ + getcchar(), setcchar(), slk_attr_set(), vid_puts(), wattr_get(),
+ wattr_set(), wchgat(), wcolor_set().
+ + Other functions call these with the corresponding altered behavior,
+ including chgat(), mvchgat(), mvwchgat(), slk_color_on(),
+ slk_color_off(), vid_attr().
+ + add new functions for manipulating color- and pair-values larger
+ than 16-bits. These are extended_color_content(),
+ extended_pair_content(), extended_slk_color(), init_extended_color(),
+ init_extended_pair(), and the corresponding sp-funcs.
+
+20170325
+ + fix a memory leak in the window-list when creating multiple screens
+ (reports by Andres Martinelli, Debian #783486).
+ + reviewed calls from link_test.c, added a few more null-pointer
+ checks.
+ + add a null-pointer check in ungetmouse, in case mousemask was not
+ called (report by "Kau").
+ + updated curs_sp_funcs.3x for new functions.
+
+20170318
+ + change TERMINAL structure in term.h to make it opaque. Some
+ applications misuse its members, e.g., directly modifying it
+ rather than using def_prog_mode().
+ + modify utility headers such as tic.h to make it clearer which are
+ externals that are used by tack.
+ + improve curs_slk.3x in particular its discussion of portability.
+ + fix cut/paste in legacy_encoding.3x
+ + add prototype for find_pair() to new_pair.3x (report by Branden
+ Robinson).
+ + fix a couple of broken links in generated man-html documentation.
+ + regenerate man-html documentation.
+
+20170311
+ + modify vt100 rs2 string to reset vt52 mode and scrolling regions
+ (report/analysis by Robert King) -TD
+ + add vt100+4bsd building block, use that for older terminals rather
+ than "vt100" which is now mostly used as a building block for
+ terminal emulators -TD
+ + correct a few spelling errors in terminfo.src comments -TD
+ + add fbterm -TD
+ + fix a typo in ncurses.c test_attr legend (patch by Petr Vanek).
+ + changed internal colorpair_t to a struct, eliminating an internal
+ 8-bit limit on colors
+ + add ncurses/new_pair.h
+ + add ncurses/base/new_pair.c with alloc_pair(), find_pair() and
+ free_pair() functions
+ + add test/demo_new_pair.c
+
20170304
+ improve terminfo manual description of terminfo syntax.
+ clarify the use of wint_t vs wchar_t in curs_get_wstr.3x
20080209
+ update test programs to build/work with various UNIX curses for
- comparisons. This was to reinvestigate statement in X/Open curses
+ comparisons. This was to reinvestigate statement in X/Open Curses
that insnstr and winsnstr perform wrapping. None of the Unix-branded
implementations do this, as noted in manpage (cf: 20040228).
